Bash it

Bash it is a collection of community bash commands and scripts. (And a shameless ripoff of oh-my-zsh 😃)

Includes autocompletion, themes, aliases, custom functions, a few stolen pieces from Steve Losh, and more.

Bash it provides a solid framework for using, developing and maintaining shell scripts and custom commands for your daily work. If you're using the Bourne Again Shell (Bash) on a regular basis and have been looking for an easy way on how to keep all of these nice little scripts and aliases under control, then Bash it is for you! Stop polluting your ~/bin directory and your .bashrc file, fork/clone Bash it and start hacking away.

Install

1. Check out a clone of this repo to a location of your choice, such as: git clone --depth=1 https://github.com/Bash-it/bash-it.git ~/.bash_it
2. Run ~/.bash_it/install.sh (it automatically backs up your ~/.bash_profile or ~/.bashrc, depending on your OS)
3. Edit your modified config (~/.bash_profile or ~/.bashrc) file in order to customize Bash it.
4. Check out available aliases, completions and plugins and enable the ones you want to use (see the next section for more details).

INSTALL OPTIONS: The install script can take the following options:

• --interactive: Asks the user which aliases, completions and plugins to enable.

When run without the --interactive switch, Bash it only enables a sane default set of functionality to keep your shell lean and to avoid issues with missing dependencies. Feel free to enable the tools you want to use after the installation.

Help Screens

bash-it show aliases        # shows installed and available aliases
bash-it show completions    # shows installed and available completions
bash-it show plugins        # shows installed and available plugins
bash-it help aliases        # shows help for installed aliases
bash-it help completions    # shows help for installed completions
bash-it help plugins        # shows help for installed plugins

Your Custom scripts, aliases, and functions

For custom scripts, and aliases, just create the following files (they'll be ignored by the git repo):

• aliases/custom.aliases.bash
• completion/custom.completion.bash
• lib/custom.bash
• plugins/custom.plugins.bash

Anything in the custom directory will be ignored, with the exception of custom/example.bash.

Themes

There are a few bash it themes. If you've created your own custom prompts, I'd love it if you shared with everyone else! Just submit a Pull Request.

You can see the theme screenshots here

Alternatively, you can preview the themes in your own shell using BASH_PREVIEW=true reload

Uninstalling

To uninstall Bash it, run the uninstall.sh script found in the $BASH_IT directory:

cd $BASH_IT
./uninstall.sh

This will restore your previous Bash profile. After the uninstall script finishes, remove the Bash it directory from your machine (rm -rf $BASH_IT) and start a new shell.

Misc

Bash Profile Aliases

Bash it creates a reload alias that makes it convenient to reload your bash profile when you make changes.

Prompt Version Control Check

Bash it provides prompt themes the ability to check and display version control information for the current directory. The information is retrieved for each directory and can slow down the navigation of projects with a large number of files and folders. Turn version control checking off to prevent slow directory navigation within large projects.

Bash it provides a flag (SCM_CHECK) within the ~/.bash_profile file that turns off/on version control information checking and display within all themes. Version control checking is on by default unless explicitly turned off.

Set SCM_CHECK to 'false' to turn off version control checks for all themes:

• export SCM_CHECK=false

Set SCM_CHECK to 'true' (the default value) to turn on version control checks for all themes:

• export SCM_CHECK=true

NOTE: It is possible for themes to ignore the SCM_CHECK flag and query specific version control information directly. For example, themes that use functions like git_prompt_vars skip the SCM_CHECK flag to retrieve and display git prompt information. If you turned version control checking off and you still see version control information within your prompt, then functions like git_prompt_vars are most likely the reason why.

Git prompt

Bash it has some nice features related to Git, continue reading to know more about these features.

Repository info in the prompt

Bash it can show some information about Git repositories in the shell prompt: the current branch, tag or commit you are at, how many commits the local branch is ahead or behind from the remote branch, and if you have changes stashed.

Additionally, you can view the status of your working copy and get the count of staged, unstaged and untracked files. This feature is controlled through the flag SCM_GIT_SHOW_DETAILS as follows:

Set SCM_GIT_SHOW_DETAILS to 'true' (the default value) to show the working copy details in your prompt:

• export SCM_GIT_SHOW_DETAILS=true

Set SCM_GIT_SHOW_DETAILS to 'false' to don't show it:

• export SCM_GIT_SHOW_DETAILS=false

Remotes and remote branches

In some git workflows you must work with various remotes, for this reason, Bash it can provide some useful information about your remotes and your remote branches, for example, the remote on you are working, or if your local branch is tracking a remote branch.

You can control this feature with the flag SCM_GIT_SHOW_REMOTE_INFO as follows:

Set SCM_GIT_SHOW_REMOTE_INFO to 'auto' (the default value) to activate it only when more than one remote is configured in the current repo:

• export SCM_GIT_SHOW_REMOTE_INFO=auto

Set SCM_GIT_SHOW_REMOTE_INFO to 'true' to always activate the feature:

• export SCM_GIT_SHOW_REMOTE_INFO=true

Set SCM_GIT_SHOW_REMOTE_INFO to 'false' to disable the feature:

• export SCM_GIT_SHOW_REMOTE_INFO=false

Untracked files

By default, git status command shows information about untracked files, this behavior can be controlled through command line flags or git configuration files, for big repositories, ignoring untracked files can make git faster. Bash it uses git status to gather the repo information it shows in the prompt, so in some circumstances, can be useful to instruct Bash it to ignore these files. You can control this behavior with the flag SCM_GIT_IGNORE_UNTRACKED:

Set SCM_GIT_IGNORE_UNTRACKED to 'false' (the default value) to get information about untracked files:

• export SCM_GIT_IGNORE_UNTRACKED=false

Set SCM_GIT_IGNORE_UNTRACKED to 'true' to ignore untracked files:

• export SCM_GIT_IGNORE_UNTRACKED=true

also, with this flag to false, Bash it will not show the repository as dirty when the repo have untracked files, and will not display the count of untracked files.

NOTE: If you set in git configuration file the option to ignore untracked files, this flag has no effect, and Bash it will ignore untracked files always.

Ignore repo status

When working in repos with a large code base Bash it can slow down your prompt when checking the repo status, to avoid it, there is an option you can set via Git config to disable checking repo status in Bash it.

To disable checking the status in the current repo:

$ git config --add bash-it.hide-status 1

But if you would like to disable it globally, and stop checking the status for all of your repos:

$ git config --global --add bash-it.hide-status 1

setting this flag globally has the same effect that SCM_CHECK=true but only for Git repos.

pass function renamed to passgen

The Bash it pass function has been renamed to passgen in order to avoid a naming conflict with the pass password manager. In order to minimize the impact on users of the legacy Bash it pass function, Bash it will create the alias pass that calls the new passgen function if the pass password manager command is not found on the PATH (default behavior).

This behavior can be overridden with the BASH_IT_LEGACY_PASS flag as follows:

Set BASH_IT_LEGACY_PASS to 'true' to force Bash it to always create the pass alias to passgen:

• export BASH_IT_LEGACY_PASS=true

Unset BASH_IT_LEGACY_PASS to have Bash it return to default behavior:

• unset BASH_IT_LEGACY_PASS

Proxy Support

If you are working in a corporate environment where you have to go through a proxy server for internet access, then you know how painful it is to configure the OS proxy variables in the shell, especially if you are switching between environments, e.g. office (with proxy) and home (without proxy).

The Bash shell (and many shell tools) use the following variables to define the proxy to use:

• HTTP_PROXY (and http_proxy): Defines the proxy server for HTTP requests
• HTTPS_PROXY (and https_proxy): Defines the proxy server for HTTPS requests
• ALL_PROXY (and all_proxy): Used by some tools for the same purpose as above
• NO_PROXY (and no_proxy): Comma-separated list of hostnames that don't have to go through the proxy

Bash it's proxy plugin allows to enable and disable these variables with a simple command. To start using the proxy plugin, run the following:

bash-it enable plugin proxy

Bash it also provides support for enabling/disabling proxy settings for various shell tools. The following backends are currently supported (in addition to the shell's environment variables): Git, SVN, npm, ssh. The proxy plugin changes the configuration files of these tools to enable or disable the proxy settings.

Bash-it uses the following variables to set the shell's proxy settings when you call enable-proxy. These variables are best defined in a custom script in Bash-it's custom script folder ($BASH_IT/custom), e.g. $BASH_IT/custom/proxy.env.bash

• BASH_IT_HTTP_PROXY and BASH_IT_HTTPS_PROXY: Define the proxy URL to be used, e.g. 'http://localhost:1234'
• BASH_IT_NO_PROXY: A comma-separated list of proxy exclusions, e.g. 127.0.0.1,localhost

Once you have defined these variables (and have run reload to load the changes), you can use the following commands to enable or disable the proxy settings in your current shell:

• enable-proxy: This sets the shell's proxy environment variables and configures proxy support in your SVN, npm and SSH configuration files.
• disable-proxy: This unsets the shell's proxy environment variables and disables proxy support in your SVN, npm and SSH configuration files.

There are many more proxy commands, e.g. for changing the local Git project's proxy settings. Run glossary proxy to show the available proxy functions with a short description.

Help out

We think everyone has their own custom scripts accumulated over time. And so, following in the footsteps of oh-my-zsh, Bash it is a framework for easily customizing your bash shell. Everyone's got a custom toolbox, so let's start making them even better, as a community!

Send us a pull request and we'll merge it as long as it looks good. If you change an existing command, please give an explanation why. That will help a lot when we merge your changes in.

Thanks, and happing bashing!
